Compare credit card extended product warranties

Why is it that expensive products work like a charm -- until three hours after the manufacturer's warranty runs out? Good news: If you paid with a credit card, you may not have to pony up for a replacement.

All four major card payment networks -- Visa, MasterCard, Discover and American Express -- offer similar (and free) extended warranties for products purchased with their cards. They can add up to an extra year to the warranty that came with the item.

Most cards offer warranty protection in some form, though you'll have to meet a laundry list of requirements to qualify. If you do, you'll get your broken toaster, cellphone or fridge back in good shape without breaking your bank account.

How to file a claim
When a product you purchased in the past year bites the dust, contact your card's warranty processing center within the allotted time to find out if they can help. (See "Compare credit card extended warranties" table below for details.) Then prepare yourself for a few hassles.

For starters, your issuer will need to make sure your product is covered. Among the possible exclusions: refurbished or secondhand items, software, cars, boats and any product you're planning to hard-wire into your house, such as ceiling fans or doorbells.

You'll also have to supply a hefty volume of documentation, including your original receipt, the relevant credit card statement and a copy of the manufacturer's warranty. Your card won't cover any kind of damage that your original warranty didn't, and it'll pile on a few of its own exclusions as well, including, for the most part, normal wear and tear, power surges, accidental damage and catastrophes such as floods.

If your broken item does qualify for extended warranty coverage, your credit card company will decide whether to repair it, replace it or reimburse you for it. You may be asked to mail in your damaged item and forced to survive without it for weeks.

On the upside, you're not paying for it, as extended warranty coverage is a free perk for cardholders. If your product malfunction happens to fall in the sweet spot -- a covered item with a covered problem that occurs within 12 months from the expiration of the original or purchased warranty -- you could save a bundle of cash. Most purchases, including biggies such as appliances, are covered up to a replacement value of $10,000. (Story continues below.)

Additional coverage
Credit card extended warranties provide an alternative to the often-criticized, but very popular, extended service contracts and warranties sold through retailers. Like credit card warranties, they have severe restrictions on what they cover. Unlike a card's warranty, they aren't free, costing an average of 10 percent to 50 percent of the items' original prices.
